When I was young and good looking it happened a few times, but I'm surprised it's the top fantasy. Lots of fun though. The first FFM one was with a couple of girls in Singapore and it was a double first as they were the first Asian girls I made love with. Before that I had a MMF threesome if you can call it that as we're both straight - me and my mate both made love to a girl in Scotland when we were students - could have been embarassing but we were good mates and slightly hammered at the time - she was a very happy girl though. I remember her name which I think is a good sign. I'm surprised it's such a low figure (3% - really??) as I thought everybody tried this kind of thing out at least once when they were young, especially MMFF - going out with a mate, copping off with a couple of girls and taking them back to the flat and swapping. Didn't everyone do that? We certainly did in the 70s and 80s. But having a scene with a couple of girls at the same time was far less common - only twice for me.
